Stiffness issues in the design of ISA displacement amplification devices: case study of a hydraulic displacement amplifier

摘要

General stiffness concepts for effective use of induced strain principles as they apply to quasi- static actuation of structures and devices are presented. The conventional induced strain actuator is first reviewed. The effect of structural elasticity is then added. Basic principles of displacement amplification are presented next. The influence of structural and amplification elasticity are then added. An example of effective induced strain actuator design with displacement amplification is provided.
